The crowding-out effect of housing subsidies on parental support: evidence from Japanese mortgage tax credits

Abstract

Children may receive monetary transfers from their parents when they attempt to purchase a home. This raises the question of whether a homeownership-related subsidy provided by government displaces transfers received from parents. The purpose of this paper is to examine this question empirically, using a sample of Japanese home-buying households that are benefiting from a mortgage tax credit (MTC) as a model case. In the empirical analysis, we offer a test of the effect of the MTC on both the extensive and the intensive margins using the overall sample as well as subsample groups. The empirical results, which use the full sample, indicate that the MTC crowds out parental transfers on both the extensive and the intensive margins. In particular, the estimates of the latter suggest an approximately 100 % displacement. Subsample analysis demonstrates that the crowding-out effect is strengthened when children are young, are of low-income group, and are living in the rental sector previously.
